(Cl. 114-05) Landing sails foraircraft intended to be taken on board ship have hitherto been arrangedat the stern of the ship. This arrangement is however not alwaysdesirable. In particular, if the arrangements for taking the aircraft onboard and for projecting it were located amid-ship for example betweenfunnels, the carrying of the aircraft from the stem to the centre of theship would be avoided. This is achieved by the present inventachment andposition of the two members extending from the point e are so arrangedthat this point e resists upwardly directed forces.

In the example of Figures -7 the spar d for the lower sail towingmembers 2 is laterally mounted 5 on the ship in the neighbourhood of thespar b for the upper towing members, for example beneath the same, andcan be swung laterally and downwardly. It can be swung in against theside 1 tion, according to which the landing sail is maof the ship by aline 4, just as can the spar b nipulated by swingable and fixablelateral spars for the upper towing members by the line 5.
